If you are an African American man and have been diagnosed with prostate cancer, you can help us better understand the significant differences that African American men have in risk factors for prostate cancer.

We now know that there isn’t any other therapy which produces a more reliable regression of both distant and local disease than androgen withdrawal (ADT).
An estimated one-fifth or more men with metastatic castration-resistant prostate cancer (mCRPC) harbor defects in genes involved in their DNA repair pathway (e.g., BRCA2, BRCA1, and others).
